ABSTRACT:
Methods and systems for performing database updates by parallel processes are presented. In one embodiment, a method may include assigning identifiers to a plurality of processes, wherein the identifiers are selected from a predefined set of identifiers, where no two processes running in parallel use the same identifier. The method may further include receiving a first request from a first process, having assigned thereto a first identifier, to update a first record in a set of records stored in a database, determining if the first record is associated with the first identifier in the database; and updating the first record if the first record is associated with the first identifier in the database. A system in accordance with an embodiment of the invention may include a processor and a memory, the memory including a set of instructions to be executed by the processor to perform a method described herein.
